Dixon wins again at Watkins Glen

Scott Dixon held off Sam Hornish Jr., series leader Dario Franchitti, Tony Kanaan and Marco Andretti over the final 14 laps and won the Watkins Glen Grand Prix in New York on Sunday, pulling away at the end by 6.2 seconds for his third straight victory at the 3.4-mile, 11-turn natural road course in the Finger Lakes region of upstate New York.

An altercation broke out when the drivers exited their cars. Hornish's father pushed Kanaan, then was knocked to the ground by members of Kanaan's Andretti Green Racing crew.

"It was unfortunate how it all played out, even after he got out of the car and I went to talk to him," Hornish said. "His point of view and mine is a lot different about what happened."
